| Nominal clutch diameter | 240 mm | Must match the original vehicle or transmission specification | Confirm whether the stated diameter refers to the friction disc or pressure plate |
| Kit configuration | Usually includes clutch disc, pressure plate and release bearing | Complete replacement set preferred for installation consistency | Verify whether pilot bearing, alignment tool or hydraulic release component is included |
| Friction lining material | Organic, low-metallic or other application-specific friction material | Stable engagement, low noise and suitable thermal resistance | Request material composition, friction coefficient data and applicable test records |
| Disc construction | Commonly a sprung-hub disc with torsion-damping springs | Reduced driveline vibration and smooth torque transfer | Check spring layout, hub profile, rivet quality and disc runout tolerance |
| Spline compatibility | Varies by application; spline count, major diameter and pilot diameter must match | Exact interchangeability with the target transmission | Provide drawing or sample measurements before production approval |
| Pressure plate type | Diaphragm-spring design is widely used in passenger and light commercial vehicles | Consistent clamp load and acceptable pedal effort | Request clamp-load curve, balancing information and release-load data |
| Balancing requirement | Dynamic balancing is commonly applied to rotating clutch assemblies | Low vibration during engine and transmission operation | Confirm balancing method, allowable residual imbalance and inspection records |
| Quality management | Automotive suppliers commonly operate under ISO 9001; IATF 16949 may apply to qualified automotive production | Documented process control and traceability | Request current certificates and confirm that the certificate scope covers clutch components |
| Product validation | Dimensional inspection, hardness checks, runout checks and functional testing are commonly used | Stable fit, engagement and service performance | Define pre-shipment inspection items and acceptance limits in the purchase order |
| Packaging protection | Individual protective packaging with moisture and impact protection | No deformation, corrosion or contamination after ocean or road transport | Confirm carton strength, palletization, moisture control and shipping marks |
| Export documentation | Commercial invoice, packing list and transport document; certificate of origin where required | Accurate customs clearance and destination-market compliance | Agree on HS classification, Incoterms, documentation language and consignee details |
| Application matching | Vehicle-specific fitment rather than diameter alone | Correct installation without modification | Match vehicle model, engine, transmission, production year and original part reference |
| Supplier evaluation method | Technical conformity, production capability, inspection system and export experience | Reliable repeat supply and consistent batch quality | Approve samples first, then use a written specification, inspection plan and warranty terms |
